3/4 and full

Recommended Posts

But what about the bore size? Remember, choke constrictions are based on the bore. So a gun with a bore of 18.4 and a 1/4 choke will shoot a lot tighter than 18.7 with a 1/4 choke!

....Just to an another layer of confusion to your choices¬†ūüėú

ive had 3/4 full   and everything in between  my scores have remained average   , I now shoot 1/4  1/2     I do wonder about the  aaa  and aa   top shots   do they honestly  shoot  3/4 full ?  if so how do they remain so consistent  ?   skillset ,  eyesight , reactions  , target reading  ?  or a combination of all  ?  or would they lie about their chokes ?    no why would they !!  

I had a former world class pigeon shooter as a mentor when I started that.  In casual conversations he always touted F/XF as the only thing to use on pigeons.  He actually shot IC and IMtoF sorta depending on the gun.  In the Mirage I used there was a #3 and fixed F.  Worked just fine

why would anyone think a aftermarket  choke is better than the manufactures original   ,    ?   :sarcastichand:

I've mentioned this to you very recently......  if the aftermarket chokes weren't better the sellers would be engaged in false advertising and we all know that is illegal!  Even tho the "proof" is apocryphal why would people not tell the truth?  Lying is a sin.  Your lack of faith in your fellow shooters is really disheartening.  :angel:

A 1/4 choke is around 10 thou . It doesn't matter what your bore size is 1/4 choke will be 10 thou tighter than the bore.

So you agree with me? 

If you start with 18.4 and reduce it by 10 thou then it will be tighter than starting by 18.7 and reducing it by 10 thou.

If you measure the end of the choke it will be smaller but not tighter.

Mmm...I would tend to agree and disagree with that, if that is possible

I would agree that a 1/4 choke is around 10 thou to the bore size, but bore size is definitely relevant.

I will give you this example. Beretta optima chokes, what size bore are the chokes made for? 18.6?

My 682 gold e is stamped up at 18.5, so a 1/4 optima choke manufactured for 18.6 barrels ain't a 1/4 choke in an 18.5 optima barrel gun. Bore size relevant.

Every gun should be made with 3/8 and 5/8 ...  then learn to use the barrel selector and the job sorted .

What happens if you shoot at Horne? You get two stands of a following pair..¬†ūü§ď

Stick in a Bior type shell.  When its that close, it opens up a couple of choke sizes instead of twiddling.  But don't think that you'll get a 2ft spread out of it!

following pair. plenty of time to open the gun and reload the same barrel.

It doesn't work like that Doug. The actual size of the constriction at the muzzle is irrelevant. Chokes work solely by the amount of constriction from the bore diameter, consequently an over bore Browning with .740" (18.8mm) bores will, all other things being equal, throw the same size pattern as an older model with .729" (18.5mm) bores. Allegedly, overbored barrels throw better patterns and have less recoil but they don't throw bigger patterns.

More specifically, chokes are actually defined by the size of the pattern they throw, not by measuring diameters. The info is all available on the www - if you're having trouble getting to sleep.

"If it ain't broken.......don't fix it!"

and that is where I am coming from, I just want to make sure I have a reasonable spread of shot for close to reasonably far!

Yesterday one of the targets was a rabbit quartering towards you and finished up under your feet, the stand was on scaffolding. When i shot with the 3/4 choke it certainly killed the rabbit but it also dug a hole about 5" wide and quite deep....ūüė≥

Hence the new thoughts about opening up the 3/4 barrel

Just wondering why you didn't use the 1/4 choke for the incoming rabbit? not that it would make a huge difference at that range

Back in the days when there were only fixed choke guns and we carried up to 3 guns around on a sporting comp, a 26'' skeet for the driven and very close crossers, normal sporting gun which was 28'' then 30'' came along and these were usually 1/4 & 1/2 or 1/4 & 3/4 and finally a 30'' trap gun  for the long stuff.

As I progressed in my competition shooting it was my Beretta 680, 30'' 1/4 & 1/2 that I used 90% of the time but a good selection of cartridges to handle the various targets. Today I use my DT10 , 32'' usually 1/4 & light mod with Eley Superb shells 9 & 7.5 shot with 9 shot on as many targets as possible.

Those early days taught me the value of different cartridges with Eley Skeet Extra veg wad being spot on for close up work and perhaps if I still shot in comps, I would take the time to test more fibre wad shells for best results on close work. 

As a side note I do recall taking my old Miroku Mk38 trap to John Bidwells on holiday one year as I had sold my sporting gun and I recall very well that I had some brilliant results on the sporting using 3/4 & full. We are down there for a week at the end of April so I may just have a day just using heavy chokes to see how well or badly I do but for sure there will be a high percentage of 9 shot in the mix.

One should be sound in the knowledge that you will never need more than 3/4 & Full.

I have shot plenty of good long targets in recent months, but I can’t actually remember when I shot a really distant edge-on target, so I haven’t needed tight choke (given that I know I have a decent pattern cartridge). Even the almost daft distance target at Coleys last Wednesday broke well once I found it.
